Sodium Erythorbate Powder CAS 6381-77-7

1. Antioxidants
By prioritizing the combination with oxygen, the oxidation of oil, pigments, and other components in food by oxygen is blocked, thereby preventing food spoilage. Adding ingredients to edible oil and fried foods can extend their shelf life; Preventing vitamin C loss and maintaining color and flavor in fruit juice and tea drinks; As an antioxidant in beer and wine, it can delay the oxidation and deterioration of the wine, remove stale odors, and enhance flavor stability. For example, adding product after beer fermentation can significantly increase the shelf life to over 6 months.

2. Color protectant and preservative
In meat processing, as a coloring agent, it can maintain the fresh red color of meat and prevent browning. The mechanism is to reduce iron ions in myoglobin and inhibit oxidation reactions. Adding 0.05% -0.3% product to pickled meat products such as sausages and ham can make the cut less prone to fading and extend the shelf life by 30% -50%. In fruit and vegetable processing, it can inhibit polyphenol oxidase activity, delay discoloration and flavor change.

For example, soaking cucumbers in a 0.3% sodium ascorbate solution can preserve them for 20 days at room temperature, with a color and taste similar to fresh products.

3. Anti corrosion and efficacy enhancing agents
By reducing the redox potential of the food system, an environment that is unfavorable for microbial growth can be created. In meat products, it works synergistically with nitrite to reduce nitrite usage by 30% -50%, while also reducing the risk of nitrosamines (strong carcinogens) formation.

In canned food, it can chelate metal ions, reduce the risk of corrosion on the inner wall of the can, and extend the shelf life to more than 2 years.
4. Food processing aids
In the production of fruit juice and jam, it can prevent the sedimentation and turbidity of fruit pulp; In frozen vegetables, it can reduce nutrient loss during the freezing process, maintain taste and color; Adding 0.02% -0.05% sodium ascorbate to pastries and bread can inhibit oxidation reactions during dough fermentation, resulting in a 10% -15% increase in product volume and a softer texture.

1. Treatment of Vitamin C Deficiency
It can be converted into vitamin C in the human body and used to treat vitamin C deficiency related diseases such as scurvy, anemia, and cirrhosis. Its antioxidant effect can alleviate liver oxidative stress and promote liver cell repair. Clinical studies have shown that daily supplementation of 500-1000mg of product can significantly improve vitamin C levels and liver function indicators in patients with cirrhosis.

2. Drug antioxidants

In local drug formulations, it can be used as an antioxidant to delay the degradation of active substances. For example, adding 0.1% sodium ascorbate to vitamin C injection can improve drug stability for more than 2 years and reduce the loss of active ingredients.
3. Urine testing contrast agent
In urine routine examination, as a contrast agent, it can exclude the interference of vitamin C on the detection of nitrite, occult blood and other items. When the vitamin C content in urine is too high, it may lead to false negative results. The addition of product can help doctors accurately diagnose the condition.

1. Rubber industry antioxidant
Can be used as an antioxidant for rubber products to improve heat resistance and aging resistance. In tire manufacturing, adding 1% -2% sodium ascorbate can extend the service life of tires by 20% -30%, reduce cracking and performance degradation caused by oxidation.

2. Textile industry reducing agents
In the process of dye reduction, it can replace traditional reducing agents (such as sodium hydrosulfite) and has the advantages of low cost and good environmental friendliness. Sodium erythorbate powder can reduce the quinone structure in dyes to hidden color bodies, improving dyeing uniformity and fastness. For example, in reactive dye dyeing, using it can increase the dyeing depth by 15% -20% while reducing the difficulty of wastewater treatment.

1. Pesticide adjuvants
Can improve the stability and effectiveness of pesticides. Adding 0.1% -0.5% product to fungicides can delay pesticide decomposition, extend the shelf life to 7-10 days, and reduce the frequency of pesticide application. At the same time, it can reduce the toxic side effects of pesticides on plants and improve crop safety.

2. Plant growth regulators
Can promote plant growth and enhance stress resistance. In vegetable cultivation, foliar spraying of 0.05% -0.1% sodium ascorbate solution can increase yield by 10% -15% and improve fruit quality. The mechanism is to regulate the redox balance in plants, promote nutrient absorption and metabolism.

1. Feed antioxidant
It can protect the nutrients such as vitamins and fats in feed from oxidative damage. Adding 0.02% -0.05% sodium ascorbate to high-fat feed such as fish meal and soybean meal can increase the oxidative stability of the feed by more than 50% and extend the shelf life to 6 months.

2. Animal growth promoters
Can promote animal growth and enhance immunity. Adding 0.05% -0.1% sodium ascorbate to piglet feed can increase daily weight gain by 8% -12% and improve feed conversion rate by 5% -8%. Its mechanism of action is related to enhancing antioxidant enzyme activity and reducing free radical damage.
